I think it's currently possible to use flash-kernel:armhf on an arm64
system to build an armhf image, and this would break that.  Given that
flash-kernel is an arch-dependent package, I think it should use the
package architecture here instead of `uname -m`.

(But since flash-kernel doesn't contain any native code, I think it
wwould be even better to make it arch-independent and to specify the
machine architecture in each entry in db/all.db.)
